To all whom it'may concern:

Be it known that I, JEFFERSON CLARK GIBSON, a citizen of the United States of America, and a resident of Chicago, county 5 of Cook, and State of Illinois, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to hydrocarbon burners, mainly those designed for use in the rfire' boxes of stoves and furnaces, and the main objects of the invention are to provide an improved form of burner including certain appurtenances of novel constructionadapted to insure efiicient opera tionand to more readily facilitate proper cleaning and care of the device; to provide a vaporizer wick of improved and more durable form adapted to better facilitate its interchange, reversal and removal from the vaporizing chamber or tube; to provide a carbon removing and cleaning attachment of improved form connected permanently in working contact with the burner or vapor jet aperture and connected for ready manual actuation from a distance; to provide an improved form of mounting for the torch cup; to provide a guide member and mixing chamber of improved form adapted to cause efficient distribution and combustion of the fuel mixture; to provide an improved form of bafiie plate or button in said mixing chamber; and to provide an improved form of closure for-the end of the burner pipe.

An illustrative embodiment of'the invention is shown in the accompanying draw ings, in which Figure 1 is mainly a side elevation of the burner and includes an edgewise View 'of the supporting plate to which it isclamped.

Fig. 2 is a section at 22 on Fig. '1 Fig. 3 is aside view of the wick member with part of the'wick properbroken away. In the embodiment shown in the drawings, the burner comprises a U-shaped tube 1 disposed with its arms 2 and 3 in a horizontal position the one over theother, the lower arm 3 beingclosed, as by the threaded cap 3, and provided with a jet aperture 4 in its upper side, and also having the starting cup 5 and'jet cleaner 6 mounted thereon. The upper or fuel supply arm 2 extends forward beyond the tip of the lower arm,

and the outer tip of said upper arm is threaded and provided with rigid mountdraw the Specification of Letters I Patent. I Pateni-jed Oct, 14, 1919 Application filed August/30. 1918. Serial No. 252.057;

ing means in the form of a pair of nuts 7 arranged for clamping the adjacent wall member 8 of the stove or other inclosing device between them for supporting the burner.

A sheet metal shield 'or flame distributer 9 is disposed on the upper side of and is secured-rigidly to said upper arm 2 directly over and coaxial with the jet aperture 4'. Said plate has numerous small perforations 10 evenly spaced'apart throughout its body and serves to spread theflame and heat and to distributesame uniformly over a large area'in a most'efiicient manner and in a form corresponding to the shape of the plate which is preferably circular. The

edges of the plate are to advantage curved downward somewhat as at 11. Said plate is clamped to the arm 2- bya pair of .U- bolts' l2, as shownclearly in the drawing. The upper arm 2 is provided also with a-wi'ck 13 of heat resistant material, preferably asbestos. Said wickis of fabricated or woven tubular character and by itself alone is flexible, but it has a rigid metal stiffening core l4,"inclosed thereby, extendperforated therefor, and looped in such manner as'to provide a closed link 16. A

manual instrument, such as a button-hook or the like, may serve as the implement 15 forengaging the ring or loop 16'to witharm 2.

The jet orifice cleaner v6 comprises a curved wire 18 which extends loosely into wick andinclosed rod from the the jet aperture 4: and is supported by an 7 agitator lever 20 fulcrumed on the lower arm 3 near said aperture; Said lever 20 is shown in the form of a sheet metal strap bentat one end to form a loop 20 which is mounted rockably for limited universal movement on arm. 3, and having .its other end extended laterally as at 20 for engagement witha rod 2 1 which extends forward through the stovefront 8 for manual operation by the attendant;

' The'lever 20 and the starting cup 5 are preferably attached to said lower arm by the same means, namely, a ring 23 surrounding said arm, and a pair, of screws 25 and 26 disposed preferably at approximately 90 to each other, the one projecting downward and supporting the cup 5, and the other being disposed horizontally and serving as a fulcrum for the agitator lever 20. Said ring 23 has threaded perforations to receive said screws which are driven inward sufficiently to set tightly against the arm 3 to secure said ring. The lever 20 has apertures 25 and 26 in its looped part 20 for said screws 25 and 26 respectively, which apertures are large enough to provide a loose fit for the screws and so permit limited movement of said agitator in all directions. The loop 20, which encircles the arm 3 and ring 23, is secured by means of a machine screw 28, and the agitator wire 18 is preferably clamped by said screw rigidly to the agitator. By this means the agitator wire may have limited universal movement and may be moved for instance longitudinally in the jet aperture and also swung crosswise and vibrated in various directions whereby all the soot and other material clogging the jet aperture may be effectively loosened and removed at the will of the operator. Being held permanently in the aperture 4, the cleaner 18 is always effective and is never out of order. I

The guide member 30, which is disposed in spaced relation over the ct orifice 4 and which also contains the mixing chamber 31, is suspended by a pair of bolts 33 provided with nuts 34 bearing on the upper side of plate 9, or the plate apertures 35 for said screws may be threaded, as will be understood, for engaging said screws. Said guide member 30 has a shape resembling the inverted frustum of a hollow cone, and is provided with a pair ofoutstanding lugs 37 at opposite sides at or adjacent to the upper edge, said lugs being perforated to receive said supporting bolts 33.

A baffle plate or button 40 is disposed horizontally in the mixing chamber 31 in coaxial relation thereto, whereby the up wardly passing vc por and flame are spread out divergently. Said plate or button 40 is carried by a transverse rod 42 the ends of which are fixed rigidly on said guide adjacent to its upper edge as at 43. Said button 40 is preferably in the form of a bolt provided with a broad flat head constituting the button proper, the shank being disposed upward and provided with a nut 45- arranged to set tightly against the supporting rod which passes horizontally through the shank of the bolt adjacent to the head, said shank being perforated at 46 to receive said rod. The supporting screws 33 are tightened sufficiently to cause the upper end of the baffie bolt, or nut45 carried thereby,

to bear against the under side of the upper arm 2 and so hold the guide and its associated parts rigidly in place.

The front end of the upper or intake arm 2 is provided with a detachable fitting 48 adapted to provide for ready access to the interior of the upper arm. For this purpose there isv provided a valve fitting of tubular character, one end of which as at 50 is conical in shape and fits tightly and wedgingly in the end of the upper arm. The conical end is also provided with an outwardly facing annular shoulder 53 to receive the pressure of the connector 55 which is interiorly threaded at one end to engage the exterior threads on the outer end of the upper arm, the opposite end being interiorly shouldered at 56 to engage the shoulder 53 of said fitting. The source of fuel is connected to said fitting by means of a small tube 57 of flexible character which may be made of metal such as copper, brass or the like. A small hand wheel 58 is arranged to open and close the valve in said fittin whereby the fuel supply is controller. lVhen the connector is unscrewed from arm 2, said fitting may be removed and moved back a considerable distance by virtue of the flexible nature of the supply tube, whereupon' the wick member may be removed and inverted or cleaned or a new one substituted.

In order that a thoroughly tight closure may be effected by the cap 3 without the use of any sealing compound, and in order that such a closure may be removed and replaced readily, a conical plug 60 is provided andadapted to fit in the end of the tube and is also adapted to'be forced tightly into place by the cap 3, said plug and tube being ground to fit.

The method of using and operating the burner described is as follows :V\ henever the burner fails to burn vigorously the operator grasps the handle 21 of the agitator control rod 21 and moves same inward and outward as well as laterally in all directions and thereby thoroughly cleans the jet aperture 4. This may be done equally well when the burner is in use as when the fuel is turned off. Although the wire 18 is always in operative position in the aperture 4, it does not interfere with the vapor and flame and never puts out the fire.

WVhenever it is thought that the wick needs attention the fuel is cut off by the valve 58 and the fitting 48 is removed. The hand tool 15 is then inserted at the open end of arm 2 and engaged with the loop 16 and the wick removed. In replacing the wick it is preferable to reverse it as the inner half receives the most heat being directly in line with the burner jet and flame, and by reversing the wick both ends are treated alike. Any deposit of carbon on the wick may be burned ofi by passing the wick through a flame while removed from the pipe 2.

The button or baffle 40 confines the flame so that it does not go out as sometimes occurs when aid baflie is omitted. The hollow cone or guide serves effectively to re duce and minimize the noise of the flame and renders it more uniform and constant and free from liability to go out.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
